l CAR-Roon.

To all whom may concern.'

Be it known that I, JOHN L. MonUN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Car-Roofs, o'f which improvement the following is a specification. v

This invention relates to car roofs, and more particularly to metal roofs for freight cars, one of the objects being to provide an improved overlapping joint between the adjacent edges of the metal roofing sheets, which will effeetually drain off the water at the sides of the car and prevent the admission of rain or moisture through the joint into the interior of the car.

Another objectl is to provide an improved fastening means or clip device for holding down the roofing sheets at the sides and ,ends of the car.

In the accompanying drawings: Figure 1 is a transverse section of a side plate and portioni'of car roof 'showing the improved clip and fastening means; Fig. 2, a side elevation of same; Fig. 3, a corresponding sectional view of the end plate andcli'p for holding down the edge of the roofing sheet at the end of the car; Fig. 4, an end elevation of the same; Fig. 5, a transverse section of an overlapping joint of the adjacent edges` of the metal roofing 'sheets taken at the car ridge and showing the running board saddle; Fig. 6, a similar section of the joint at a point nearer the eaves of the car; Fig. 7, a transverse section of a portion of the car roof taken through the joint between adj acent roofing sheets; and Figs. 8, 9 and 10,

detail views showinf)- modified forms ofoverlapping joints' of the metal roofing sheets.

According to the construction shown in Figs. 1 and 2, the improved fastening orclip for holding the roofing sheet, 11, upon the side plate, 12, comprises a casting, 13, having a projection, 14, extending over the roofing sheet and side plate, and also provided with a flange or socket, 15, projecting `from its inner side within a recess formed in the fascina, 16, on which the clip is mounted, the socket engaging the head of a bolt,

17, passing through the fascia and side plate for securely fastening the clip and fascia in position.

Specification of Letters Patent.

It will be understood that the I socket flange is open on one side at least for Patented Oct. 5, 1915 Application filed December 19, 1912. Serial No. 737,668.

inserting the bolt head into the vsocket before applying the clip to the fascia. The fascia is preferably secured to the side plate below the top thereof, and the end of the rooflng sheet may be bent down over the side plate and extend over the upper inclined face of the fascia, there being a suiiicient clearance between the downturned flange of the roofing Jsheet and the side of the frame l or plate to give the desired flexibility of the ro'of. The clip is also set away from the side plate and roofing sheet at this point in order to permit o'the sheet to move relative to the frame of the car.

By using the socket flanges, 15, sunk into the fascia, the outer face of the clip may be smooth and unbroken so that there is no chance for the entrance of moisture through the clip to the space around the bolt head or bolt in the fascia, and as the clip is also set in flush with the outer line of the fascia, all the connecting parts are within the usual clearance lines as determined by the fascias at the sides of the car.

For the purpose of preventing any water from draining down over the fascia to the inside face of the clip, the extreme lower end of the roof sheet may be bent up at this point in the* form of a deflecting flange, 18, to divert the drainage water to either side of the clip, thereby excluding all moisture from the joint around the bolt head socket within the fascia. The clip may be provided with a depression, 19, for engaging the roofing sheet joint above the fascia to assist ,in holding the roofing sheet in position. This improved elip construction may also be employed upon the fascia` at the end. of the car where it is secured to the end frame or plate, 12, as shownin Figs. 3 and 4, of the drawings.

In case the roofing sheet does not lie close to the frame plate at the point where it is desired to fasten the clip, a depression may be formed in the roofing sheet at this position, as shown in Figs. l and t?, and such depression may be of any desired length, or extend all the way to the car ridge, if preferred. The clip may also be provided with a flange, 20, extending down upon the sheathing and fastened with a bolt, 2l, if desired.

According to another feature of my improvement, the roofing sheets are designed to halve overlapping side edges extending transversely of the car roof, one edge being formed with a drain trough, 22, and the eontiguous edge of the adjacent sheet being formed to extend over said trough and const'itute a cover or cap section, 23, therefor, as shown in Figs. lith this construct-ion, the several roofing sheets are preferably, but not necessarily, designed to extend the full width of the car from eaves to eaves, and in such case, the

running board saddle, 24, may be mounteddirectly upon the cap section, 23, at the ridge and secured thereto by one or more bolts, asv shown in Fig. The bolts being located over the trough section, 22, any leakage of water through the cap sections at the bolt holes will readily drain down through the trough and over the eaves of the car.

If preferred, the trough portions may be flared out and made shallower from the ridge toward, the eaves, as indicated by the sect-ions shown in Figs. and 8. The trough and cap sections may be formed in a variety of ways in the adjacent edges of the roof sheets. As shown in Figs. 5 and (3, the edge having the trough, 22, is also provided with a shallow depression, 26, into which the extre-me side edge of the cap sheet is turned and flanged as indicated at 27, while another depression, 2S, may be formed at the edge of the'trough sheet, above which there is a slight downwardly projecting rib, 29, formed in the cover sheet.

According to the construction shown in Figs. 8, 9 and 10, the bottom of the trough section is in substantially the same plane with. the body portion of the sheet, and is formed by a. vertical rib7 30, spaced from the turned up edge, 3l., which also has a substantially horizontal flange, 32, at its upper end, while the cap portion is formed by bending the same upward into a substantially rectangular section over the trough and forming a flange, 33, to bear upon the roofing sheet beyond the rib, 30. The top portieri of the cap may also be provided with a depression, 34, if desired, for assisting to deflect any water which might 'possibly pass over the rib, 30, downward into the trough. i

lt will now be seen that with any of these improvedforms ot' joints between adjacent roofing sheets, any water which may be driven into the joint will be efFectua-lly drained off at the eaves without permitting access of moisture to the interior of the'car, and the trough and cap portions will always occupy their proper positions, while at the same time, dispensing with the use of 5 to 10, of the drawings. l

additional and separate parts for this purpose. Y

Having now described invention,what I claim as new. and desire to secure by Letters Patent is l. In a car roof, the combination of metal roofing sheets with overlapping edges located transversely of the car, one of said edges being shaped to form a drain trough and the other edge extending over and constituting a cover for said trough, a running board saddle, and fastening bolts therefor extending through and bolted to said cover portion over said' trough.

2. A car roof, the combination with a frame member, and a fascia having anfinclined surface below the top of said frame member, of a` metal roofing sheet. supported on said frame and having ,its end turned down over the inclinedsurface of the fascia, and a metal clip fastened to the fascia and having projections for holding the metal sheet down upon the frame member and upon the fascia.

3. In a car roof, the combination with a frame member and a fascia, of a metal roofing sheet supported on said member, a metal clip mounted on said fascia and extending over said roofing sheet, said clip also having a. socket on its inner face projecting into a recess in said fascia, and a bolt having a head located in said socket and extending through the fasciaI and the frame member.

l. In a car roof, the combination with a frame member and a fascia, of a roofing sheet having its end turned down over the frame and extending over the fascia, and a metal clip fastened to the fascia and extending over the roofing sheet for holding the same in position, the end of said sheet upon the fascia being turned up to form a deflect- 'ing flange beneath the clip.

5. In a car roof, the combination with a frame member and a fascia, of a roofing sheet having its end turned down over the fra-me and extending over the fascia, a metal clip mounted on said fascia and Hextending over the roofing sheet, and a bolt connected to the inside of the clip for fastening the same to the fascia and frame member, the end of the roofing sheet upon the fascia being turned up to form a. defiecting flangebeneath the clip. l

In testimony whereof have' hereunto set my hand.
